Doing easy elementary science projects with the kids can be fun and it does not only have to be done for science fairs. Kids love learning in a fun “Play” way and we can use easy elementary science projects to teach them about the wonders of science without them actually realizing that they are learning. Doing easy elementary science projects with the kids is also a great way for homeschoolers to teach the kids science. I think we must start doing a lot more “little” projects with the kids. Here are a few short fun ones to do with the kids.

Physical changes easy elementary science projects

Physical changes can happen when two substances interact or when energy is applied to one or

more of the substances. In this easy elementary science projects we are going to see how substances change and then we are going to reverse the physical changes.

The salt solution physical change experiment

What you need for this science project:

• Salt
• A measuring cup
• A teaspoon
• A heatproof glass or container
• Water

How to do this easy elementary science experiment:

1. Pour ½ cup of warm water into your glass or container
2. Dissolve 2 teaspoons of the salt into the warm water
3. What happens now? The salt becomes invisible, this is a physical change.
4. Now place the glass in a warm place and leave it for a few days until all the water has evaporated.
5. Observe what has happened. The water evaporated and the salt was left behind in the glass.
6. Once again a physical change took place. The salt is now visible once again.

The rock candy physical change experiment

In this easy elementary science project we are going to do more or less the same with a sugar solution.

What you need for this science experiment:

• A small heatproof container such as a beaker
• A piece of string long enough to hang to the bottom of the beaker
• ½ Cup of hot water
• 1 Cup of sugar
• A pencil

How to do this experiment:

1. Dissolve the sugar in the water in your beaker
2. Once again observe the physical change
3. Tie the string around your pencil and place the pencil over the top of the beaker so the string dangles in the water.
4. Leave your beaker in a hot dry place for a few days and observe what happens.
5. Sugar crystals start forming on the string, a physical change again.
6. There you have your rock candy!

A salty work of art easy elementary science project

In this experiment we are going to have fun. This experiment can double up as an easy kids craft as you will be making a lovely painting.

In this experiment we are going to show how salt and food coloring dissolves in water and reverts back when the water evaporates. You will be amazed at the beautiful painting you will end up with. This experiment needs a little more preparation, but is well worth the trouble.

What you need for this experiment cum craft:

• As many containers as colors you intend to use
• Warm water
• As many colors food coloring as you want to use
• Lots of salt
• Thick paper
• Paint brushes

How to do this experiment:

1. First you have to mix salt into your warm water until it will hold no more salt (it is called a saturated solution)
2. Now divide this salt solution into your containers.
3. Add the food coloring to the water. Make it strong so the colors will come out really well.
4. Using your paint brushes make a painting on your paper. Put it on thick so that there is really lots of salt and coloring.
5. Leave your painting in a warm dry place until all the water has evaporated.
   Now you can observe the salt crystals and the food coloring that remains behind after the water has evaporated.
6. A Physical change again, reversing the first one.
7. Observe the beautiful patterns the food coloring makes around the salt crystals.
8. Now you have a beautiful work of art as well as a science experiment.

I hope the kids will enjoy these easy elementary science projects and really have a fun learning experience.

Cool Science Fair Projects – The Power Of Growing Flowers

This is one of our cool science fair projects that show the strength of growing plants.

What you need for this science fair project:

• A sheet of clear plastic
• A healthy potted plant
• A box of paper clips
• 2 Small boxes just a bit higher than the plant

How to do this cool science fair project:

1. Take your healthy potted plant and place it on a windowsill that gets enough sun.
2. Now you place the two boxes on each side of the plant taking care not to shade the plant.
3. Lay the plastic across the boxes and let it hang down the two sides of the boxes.
4. Make two chains that are identical with the paper clips
5. Lay these chains over the clear plastic so that it hangs down the sides of the boxes.
6. Arrange them evenly and mark their positions on the boxes.
7. Now you care for the plant as normal.
8. Check and mark the positions of the chains from time to time

What has happened?

• Make note of what happens?
• Measure the markings as they move up the boxes.
• Why do the chains move up?

Explanation:

This experiment shows us how strong plants are. As the plant grows it pushes the plastic and thus the chains up. Now you can see how plants can be so incredibly strong and grow through blocks of cement and why weeds push through the sidewalk cracks to reach the light (Plants need light to stay alive and grow)

This science project is one of our examples of science fair projects where you actually proof two related characteristics of air. You will prove that air has weight and that, because of the weight, air pressure is strong enough to bend a can. We are going to use the principle that as air heats up; it has a greater volume and if it is in a container some of the air will escape from the container. Then by screwing a top on the container we are going to prevent the air from going back in when the container cools down.

CAUTION: This example science fair project must be done with adult supervision as heat is used.

What you will need for this experiment:

• Large container
• A can with a screw top (you get cans of olive oil that will be the ideal can)
• Water
• Stove
• Oven mitts
• Ice
• Dish cloth
• A scale
• Note book
• Pen
• Camera

How to do this science experiment:

1. For your display, it is a good idea to take a photo of the can in its original state.
2. Fill the large container with water and ice and put it to one side until you need it.
3. With a finely calibrated scale, weigh the can with the screw top on.
4. Make a note of this weight.
5. Remove the screw top.
6. Put the can on the burner on the stove.
7. Heat the can until it is very hot.
8. Using the oven mitts, remove the can from the stove and, working quickly, screw the top on the can and place it in the cold water.
9. Observe what happens, write it down and take a photo.
10. When the can has cooled down, wipe it dry and weigh it.
11. Make a note of the weight and take a photo.
12. What has happened?
13. Why do you think it happened, remember we said in the beginning that we are going to prove two things?

What happens is that the air pressure bends the can. Why can we say that? What did we do to remove air from the can so that the air pressure on the outside is more than in the inside?

The other thing that happens is that the can now weighs less. Why is that? Think of what we have done with the air in the can.

This is just one of our many examples of science fair projects. For more fun and easy examples of science fair projects visit our site Easy Science Fair Projects.
